In a recent Web interview with Hideo Kojima, the master of all things Metal Gear Solid explained that creating Metal Gear Solid 4 is technically possible on Xbox 360.

Kojima said with the exception of nuances or small details, the power of next generation hardware (and the PC) no longer provides the technical restrictions they did before. Kojima also explained in a sideways manner why the Xbox never saw a version of Metal Gear Solid Snake Eater. He explained that he has no grudge or dislike for the Xbox or Xbox 360, but last year he and his team had their hands full with MGS3. Other Konami teams, he said, were able to get their hands on the Xbox 360 tools before him. It's his philosophy that he wants to be first, not second on the early development for a system, which is why he chose PS3.

When IGN contacted Konami America today, the representative said, 'there are no new developments or news to share about any Metal Gear products coming to Xbox or 360.'
